Sugar-powered biobattery has 10 times the energy storage of lithium: Your smartphone might soon run on enzymes | ExtremeTech

As you probably know, from sucking down cans of Coke and masticating on candy, sugar — glucose, fructose, sucrose, dextrose — is an excellent source of energy. There is a reason why almost every living cell on Earth generates its energy (ATP) from glucose. Now, researchers at Virginia Tech have successfully created a sugar-powered fuel cell that has an energy density of 596 amp-hours per kilo — or
